Purpose Research on developmental language disorder (DLD) in adulthood has increased rapidly in recent years. However, to date, there has been no systematic literature review on this topic, thereby limiting the possibility to have a comprehensive overview of publications in this field. Method Following Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines, we conducted a systematic literature review. A literature search was undertaken in four databases, from 2005 to 2018. We selected articles with original data related to life outcomes of young adults with and without DLD, all aged between 18 and 34 years, in three life areas: education, employment, and independent living. Methodological characteristics of the studies were analyzed. Results Fifteen articles were selected with longitudinal designs. In every life area, young adults with DLD were compared to their typically developing peers to identify their strengths and weaknesses. The predictive role of language abilities was also examined. Conclusions Outcomes within each life area are heterogeneous. Nevertheless, similarly to young children and adolescents, young adults with DLD face numerous challenges. Although language abilities partly predict some of these outcomes, much of the variance remains unaccounted for and some outcomes are unrelated to this predictor. This systematic literature review has implications for researchers and practitioners to identify promising avenues for research, interventions, and policy development.

目的 近年来，关于成年期发育性语言障碍（DLD）的研究迅速增加。然而，迄今为止，尚未有关于该主题的系统文献综述，从而限制了全面了解该领域出版物的可能性。方法 遵循系统评价和Meta分析的首选报告项目（PRISMA）指南，我们进行了一项系统文献综述。在2005年至2018年期间，在四个数据库中进行了文献检索。我们选择了与年龄在18至34岁之间、患有和未患有DLD的年轻人在教育、就业和独立生活这三个生活领域的生活结果相关的原始数据的文章。分析了这些研究的方法学特征。结果 选择了15篇具有纵向设计的文章。在每个生活领域，将患有DLD的年轻人与其发育正常的同龄人进行比较，以确定他们的优势和劣势。还研究了语言能力的预测作用。结论 每个生活领域的结果都是异质性的。然而，与幼儿和青少年一样，患有DLD的年轻人面临着众多挑战。尽管语言能力部分预测了其中一些结果，但仍有很大一部分方差无法解释，并且一些结果与该预测因素无关。这项系统文献综述对研究人员和从业者确定研究、干预和政策制定的有前景的途径具有启示意义。补充材料 https://doi.org/10.23641/asha.13022552 。
